Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): David Twichell

Affiliate Investigator(s): Dick Poore and Lisa Osterman, USGS-St. Petersburg

Information Specialist(s): David Twichell

Data Type(s): Location-Elevation: Navigation, Sampling: Geology, Seismics: Boomer

Scientific Purpose/Goals: High-resolution seismics, surface sediment sampling, and vibracoring.


Start Port/Location: Apalachicola, FL

End Port/Location: Apalachicola, FL

Start Date: 2009-07-08

End Date: 2009-07-13

Equipment Used: Grab sampler, HYPACK, Boomer, Single channel hydrophone, Alpine Vibracorer

Information to be Derived:

Summary of Activity and Data Gathered: The cruise was divided into two parts. Chirp seismic profiles were collected on the inner shelf offshore of Apalachicola Bay during July 8-10. Seismic data were collected along approximately 93 km of tracklines. Vibracores and surface sediment samples were collected in the bay and offshore of the bay during July 11-12. Vibracores were collected at 10 stations and surface sediment samples were collected at 8 of these stations and four additional ones where vibracores were not taken.
